Abstract
Description
Technical Field
[0001] This invention relates to the field of coffee machine technology, and in particular to a sealing device applied to the coffee powder container assembly of a coffee machine. Background Technology
[0002] Coffee, a beverage made from roasted and ground coffee beans, is increasingly popular around the world. The resulting "coffee culture" permeates every aspect of life. Whether at home, in the office, or at various social occasions, people are enjoying coffee, which has gradually become associated with fashion, modern life, work, and leisure.
[0003] With the rapid development of society and people's ever-increasing material needs, coffee machines have emerged. The basic structure of a coffee machine includes a grinding assembly, a tamping assembly, and a powder receiving hopper assembly.
[0004] The grinding assembly is used to grind coffee beans into fine coffee powder; the tamping assembly is used to tamp the ground coffee powder into a coffee pouch; and the receiving hopper assembly is used to move the coffee pouch and coordinate with other components to form coffee liquid, while transferring the coffee liquid to a coffee cup.
[0005] During the coffee delivery process, the coffee container assembly needs to work in conjunction with the dispensing pipe. A sealing structure is installed between the coffee container assembly and the dispensing pipe to prevent coffee leakage during the delivery process.
[0006] Because the powder receiving cylinder assembly needs to rotate, existing sealing structures often use multiple parts working together to ensure a good seal.
[0007] However, some shortcomings still exist in actual use:
[0008] 1. Sealing with multiple parts means that the manufacturing cost of the sealing structure is high, which in turn increases the selling price of the coffee machine, making it difficult for the coffee machine to capture the market.
[0009] 2. The sealing method using multiple parts means high maintenance costs. If one of the parts is damaged, the entire sealing mechanism needs to be repaired, reducing the practicality of the coffee machine. Summary of the Invention
[0010] This invention provides a sealing device for use at the coffee powder cartridge assembly of a coffee machine, which solves the problem that the sealing ring structure at the coffee powder cartridge assembly and liquid outlet pipe of coffee machines on the market is complex, resulting in increased costs and inconvenience for maintenance.
[0011] A sealing device for use at the coffee machine powder container assembly, comprising the powder container assembly.
[0012] The powder receiving cylinder assembly is snapped to one side with a bracket, and a liquid outlet pipe is provided on one side of the bracket;
[0013] The powder receiving cylinder assembly has a liquid outlet on one side connected to the bracket, and a sealing ring is connected to the liquid outlet. The other side of the sealing ring is connected to the liquid outlet pipe.
[0014] The powder receiving cylinder assembly is rotatable. During the rotation of the powder receiving cylinder assembly, one side of the sealing ring seals the liquid outlet, thereby achieving a seal on the powder receiving cylinder assembly.
[0015] A pressure plate is provided between the sealing ring and the powder receiving cylinder assembly, and the pressure plate is used to fix the sealing ring and the powder receiving cylinder assembly.
[0016] Preferably, the bracket has a bracket shaft hole, and two sets of bracket screw holes are formed around the bracket shaft hole.
[0017] Preferably, the pressure plate has a pressure plate shaft hole, and two sets of pressure plate screw holes are provided around the pressure plate shaft hole. A surrounding rib is provided on the side of the pressure plate shaft hole near the sealing ring.
[0018] Preferably, the two sets of pressure plate screw holes on the pressure plate correspond to the two sets of pressure plate screw holes on the bracket, and screws are passed through the two sets of pressure plate screw holes and the two sets of pressure plate screw holes to realize the threaded connection between the pressure plate and the bracket.
[0019] Preferably, the pressure plate shaft hole is connected to and communicates with the liquid outlet.
[0020] Preferably, a space is left between the bracket and the pressure plate, the sealing ring is disposed in the space, and a short shaft is provided on each side of the sealing ring, wherein one of the short shafts is inserted into the bracket shaft hole on the bracket, and the other short shaft is inserted into the pressure plate shaft hole on the pressure plate.
[0021] Preferably, the reinforcing bar surrounds the other short shaft, and the reinforcing bar is made of an elastic material. The reinforcing bar compresses the other short shaft to reinforce the sealing ring.
[0022] Preferably, the outlet pipe is L-shaped, with an inlet hole at one end and an outlet pipe screw hole above the inlet hole. The outlet pipe screw hole is fixed to the side of the bracket away from the powder receiving cylinder assembly by screws, and an outlet hole at the other end of the outlet pipe, through which coffee liquid flows to the outside.
[0023] Preferably, the sealing ring has a sealing ring shaft hole, which is connected to and communicates with the pressure plate shaft hole, and one end of the liquid inlet hole is inserted into the sealing ring shaft hole.
[0024] Preferably, the coffee liquid seeps out from the outlet of the coffee powder receiving cylinder assembly, passes sequentially through the outlet, the pressure plate shaft hole, the sealing ring shaft hole and the inlet hole, and finally flows out from the outlet.
[0025] The powder receiving cylinder assembly can rotate left and right around a preset center. During the rotation of the powder receiving cylinder, the liquid outlet moves with the powder receiving cylinder assembly and moves to the pressure plate sealing area. At this time, the liquid outlet is blocked by the pressure plate sealing area, thereby achieving sealing during the rotation of the powder receiving cylinder.
[0026] The coffee liquid seeps into the coffee dispenser assembly, then flows through the outlet into the sealing ring, and finally flows out from the outlet tube. The sealing ring acts as a connector, allowing the coffee liquid to flow from the coffee dispenser assembly to the outlet tube. The coffee dispenser assembly can rotate in both directions, and during this rotation, the sealing ring completely covers the outlet of the coffee dispenser assembly, achieving a complete seal.
[0027] Compared with the prior art, the advantages of the present invention are as follows:
[0028] 1. The device of the present invention achieves a sealing effect by cooperating with the sealing ring, the powder receiving cylinder assembly and the liquid outlet pipe. The sealing ring covers the side wall of the liquid outlet pipe, sealing the liquid outlet pipe on one side and sealing the liquid outlet of the powder receiving cylinder assembly on the other side.
[0029] 2. The device of the present invention achieves a seal during the rotation of the powder receiving cylinder assembly and the pressure plate by means of mutual cooperation between the powder receiving cylinder assembly and the pressure plate. The powder receiving cylinder assembly can rotate in both directions. During the rotation of the powder receiving cylinder assembly, the liquid outlet rotates accordingly. At this time, the pressure plate and the sealing ring are stationary. The liquid outlet moves to the closed area of the pressure plate and is blocked by the closed area of the pressure plate, thereby achieving a seal during the rotation of the powder receiving cylinder.
[0030] 3. The device of the present invention, through the cooperation between the pressure plate, the powder receiving cylinder assembly and the sealing ring, ensures that the sealing ring is fixed by the surrounding ribs on the pressure plate during the movement of the powder receiving cylinder assembly, thus preventing leakage from the device.
[0031] 4. The device of the present invention adopts a combination of pressure plate and sealing ring to seal the powder receiving cylinder assembly and liquid outlet pipe. When coffee liquid leaks out of the device, the fault point can be identified by checking the fit between the pressure plate, sealing ring and other structures, and further repairs can be carried out, which greatly simplifies the maintenance process of the sealing device.

[0157] Please see Figure 15The image shown is a view of the coffee liquid flow path according to the present invention.
[0158] The coffee liquid seeps out from the outlet 11 of the powder receiving cylinder assembly 1, passes through the outlet 11, the pressure plate shaft hole 51, the sealing ring shaft hole 41 and the inlet hole 31 in sequence, and finally flows out from the outlet 33.
[0159] In this embodiment, coffee liquid seeps into the coffee powder container assembly 1, then flows into the sealing ring 4 through the outlet 11, and finally flows out from the outlet pipe 3. The sealing ring 4 serves as a connector, enabling the flow of coffee liquid from the coffee powder container assembly 1 to the outlet pipe 3. The coffee powder container assembly 1 can rotate in both directions. During the rotation of the coffee powder container assembly 1, the sealing ring 4 can completely cover the outlet 11 of the coffee powder container assembly 1, achieving a complete seal.
[0160] This invention is based on a sealing device applied to the coffee powder container assembly 1 of a coffee machine, and has the following advantages:
[0161] 1. The device of the present invention achieves a sealing effect by the cooperation between the sealing ring 4, the powder receiving cylinder assembly 1 and the liquid outlet pipe 3. The sealing ring 4 covers the side wall of the liquid outlet pipe 3, and the sealing ring 4 seals the liquid outlet pipe 3 on one side and the liquid outlet 11 of the powder receiving cylinder assembly 1 on the other side.
[0162] 2. The device of the present invention achieves a seal during the rotation of the powder receiving cylinder assembly 1 and the pressure plate 5 through mutual cooperation. The powder receiving cylinder assembly 1 can rotate in both directions. During the rotation of the powder receiving cylinder assembly 1, the liquid outlet 11 rotates accordingly. At this time, the pressure plate 5 and the sealing ring 4 are stationary. The liquid outlet 11 moves to the closed area of the pressure plate 5. At this time, the liquid outlet 11 is blocked by the closed area of the pressure plate 5, thereby achieving a seal during the rotation of the powder receiving cylinder.
[0163] 3. The device of the present invention, through the cooperation between the pressure plate 5, the powder receiving cylinder assembly 1 and the sealing ring 4, ensures that the sealing ring 4 is fixed by the surrounding rib 53 on the pressure plate 5 during the movement of the powder receiving cylinder assembly 1, so as to prevent leakage of the device.
[0164] 4. The device of the present invention uses a combination of pressure plate 5 and sealing ring 4 to seal the powder receiving cylinder assembly 1 and liquid outlet pipe 3. When coffee liquid leaks out of the device, the fault point can be identified by checking the fit between pressure plate 5, sealing ring 4 and other structures, and further repairs can be carried out, which greatly simplifies the maintenance process of the sealing device.
[0165] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, the technical features mentioned in the various embodiments can be combined in any manner as long as there is no structural conflict. The invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
